Make virtual machine from many physical PCs


Hi everybody,

Is there any way (except of ScaleMP) to take many pysical PCs (nodes) and install a single virtual machine that will use all the processors & memory of all those nodes?

As far as I know VMware has it's hypervisor that called "ESX" that should be installed on each physical machine (node) and the vCenter make it possible clustering between all the ESXs (all the nodes) and than it possible (again as far as I know) to create virtual machine that uses all the nodes's hardwares(cpu, memory, etc).
Then i thought, if it's really possible via VMware, does somebody knows how to do the same via Xen for example?

I saw some thread here in this forum, but not something usefull. below:

Thanks,
Gal.

Hi,

VMWare does not support such a configuration. The maximum hardware used by a virtual machine in VMWare and Xen is limited to the hardware provided by the physical machine the VM is running on.

So, do you know about an other way to make it work?
What I actually need is make Matlab work on many physical PCs. ATM my matlab works on all the cores in my PC, thats why I wanted to create single OS that use many physical PCs resources.

Hi,

did you check if this software will work on an high performance computing cluster?

Took the words from my fingers. And yes, Beowulf is alive and well (bestill my heart!). It's located here http://www.beowulf.org/

What you are attempting to do is not possible on any current virtualized platform, and to be honest, violates all HA best practices. You'd be much wiser to run many "node" VMs on clusters of ESX servers.

This should also be of some assistance http://www.unicluster.org/

Hope this helps.
